I have a 93 JGC 5.2 V8 all wheel drive (249 tc), there is a bad vibration in all gears, the vibration is bad only when the throtle is at the normal driving range..ex if you let off it goes away or if you give it gas it goes away, I removed the front drive shaft and there was no change, I took it to a garage and had the rears check, they were good, I put 4 new tires and 2 new wheels on it (all balanced). PLEASE LET ME KNOW IF YOU HAVE EVER HEARD OF SUCH A PROBLEM, ANY HELP WOULD BE GREAT
THANKS

What speed are you traveling at when you first notice it??

Where do you feel the vibration coming from in the vehicle??

ANY SPEED IN ANY GEAR, IT GETS WORSE IN HIGHER GEARS, OVERDRIVE FEELS LIKE YOR DRIVING OFF THE RAILROAD.
TRANS OR TRANSFER CASE, BUT I HOPE NOT

well it sounds like driveshaft vibration - did you put a lift kit on, did you ever remove the rear driveshaft? it might not be placed back right 0 tis is important to keep it balanced.

no i have not, I'll try that, do you know anything else it could be?
thanks

If you haven't installed a lift kit or disconnected the driveshaft then driveshaft vibration wouldn't be the problem.

Does it make any wierd noises or anything - during the vibration period?

no their are no odd noises, I purchaced it from a salvage yard, so the drive shaft could have been removed, I'm pretty sure someone put a transfer case in it.
